Yep. Looks like the AI models. I’m going to try to be happy for the SC crew.

It's crazy that this starts in just over 24 hours and we don't know if GSO-RDU getting 6" or CAE to MYR is getting 6". Both areas aren't getting 6"...somoeone going to be disappointed. I took the afternoon off from models and I come back and the first model I look at is the 18z Euro which has the precip min for all of NC around Raleigh....the entire state of NC, Raleigh is shown with the least of amount of precip. 🤦‍♂️

I can't ever recall an event this close with this spread among models...

Anyone know how well RDU handles snow? Have a flight Sunday AM, wondering if I need to reschedule
I’m not sure but I would imagine not well. The one saving grace is the snow will be powder and not the snow we normally get.

This is 4 runs in a row of the euro showing more than 6 inches here. Even though technically it was a tiny decrease from the previous run, it looks more like noise as the low track was nearly identical. It's interesting that i don't see evidence of the snow band across ne ga that the other models are showing so i'm not sure what the deal is there. One thing seems certain, the upstate is in a great spot.

btw, for the upstate folks.

As a rule of thumb I would cut those in half.

I have my expectations in check but it's hard to ignore the model agreement for my local, the track of the upper level low, and the track of the mid level lows. 3 inches is the floor i expect for this event and probably would be a little disappointing. My general thought is 4 to 6.
 
If I could erase that stupid dip along the NC/VA border once and for all 🤦‍♂️
This storm feels like the opposite of Jan 3-4 2018 for me. That one had a last minute deform band sit up over me here and i ended up at 11in where people 20 miles away got just 4in.

Personally not feeling too good with every model looking to show a precip min just east of I-95 right along the border. I have some hope the obvious NW trend happens towards gametime but im not sure it would benefit with how dry it is up this way.
 
Any other winter event like this would tick NW and verify NW of modeled…but this one fighting like an infectious disease.
I just realized though, it got the .5 qpf almost always to Va line. Can you run a trend gif? I can't figure out how to make that happen on SV yet

I’m still waiting on that tick. There’s been some things turning our way this afternoon. But I’d like to see the SC folks score as well and everyone win.
I dont think this is ticking north…it’s remarkable how stubborn that 50/50 is. It just won’t move out…never seen anything like it. Every single winter storm we’ve ever had that has lifted out quicker than modeled as we approached go time. But not this time…

You're in a bullseye that's pretty safe imo
That swath of 10" at @Stevo24 house has been inching closer to Oconee every run.
I feel pretty good here too.
It's like being a 5 year old at Christmas time with all these great runs in the Western Carolinas!
BOL to everyone so long as it doesn't interfere with my foot of snow!!!
🤣🤣🤣

In ran away during the last storm. Moved 100 miles north every model run for the last 72 hours
